Can the12VDC light be connected directly to a 12 car battery that is powered/charged by a 45 watt solar panel?

Theoretically yes.. however you may have to find a way to disconnect solar panel when light is in use and charge battery with light disconnected. If both are hooked up in parallel with battery, it's basically a direct line from panel to light which could cause complications.

No ! the car 12 volts is actually between 13.2 to 14 volts.On my garden tractor 2 10 Watts light, I had to connect a seal beam in series to reduce the current to 1.6 amps for 2 lights.Do not exceed 0.9 Amp each led, I am running about 0.8 amp and the led are full brightness.Regards Yvon224

yes, the light can use 10-30 vdc so your car battery is 11-14 vdc. mine are directly connected to 24v batteries. my PV panels run through a charge controller.

The solar panel itself has a 12 volt cable built in, and it includes a separate 12 volt car charger adapter that connects to it (allowing you to plug your phone/tablet's car charger into the solar panel directly.)

No... 12 volt DC only ( used on auto battery or 12 volt lawn light system).

only if you use a 12v charge controller and have you batteries wired in series. the output of the panel under load is a bit over 24v.

The panel can supply 12v dc. If your device can charge off of this voltage, you would be ok. Not sure how long it takes to charge though.

Short answer, yes. Just wire it up like how you would a light bulb; make sure to add a resistor, this thing only take 12volts DC only.

Yes, the Inverter should hook directly to the battery, with very large cables. You can run your low wattage dc loads off the Renogy 30 amp charge controller. I run some 12 volt dc lamps off the charge controller. See the diagram on Renogy's web site for an example... Follow the hookup order for the cables to the charge controller

Its only a 5 Watt panel so no. Running something from a solar panel, without a DC battery, isnt practical anyway if you need any sort of a constant voltage.

set up properly, this would work to charge any 12v battery. you may want to work in a solar charge controller if you are worried about overvoltage protection and other features that can add safety. one thing this will probably not do is bring a dead car battery back to life, if that is the nature of your question. BTW... I have successfully done this with this very panel, and a small 12v 7ah battery. A few good hours of sun will give you a good recharge trickle, but its not much power (smaller panel). You may want to consider a deep cycle battery if you intend to use the battery over and over after recharges. Hope this helps.

The instructions doesn't give enough explanation. I called the company for my inverter and asked if solar is compatible with their inverter hooked up to the charge controller. They said to keep the inverter connected to the battery. The only thing I can think of is using a 12 volt light or a small apliance could be connected directly to it instead of using the battery power. If a 12 volt light is connected directly you are taking advantage of the solar imediatly. If the same light was connected to the battery instead, the charge controller doesn't let the solar charge the battery until it drops to a certain voltage. So solar panel isn't being used to its full advantage.

yes you can since the maximum output power of this specific battery is = 125 x 11.1 = 1387.5 W = 1.38 kW and since the light you chose is operating on 12V so you are good to go :)and i think this will give your light something between 40-50 minutes of continues discharging until the battery reaches 9.6V which is the minimum voltage you can reach without harming the battery

Of course you can use these lights with your 12-volt system directly from the battery. I have used them most successfully here in the Sierra Tarahumara and even with vehicles to provide light while camping. The minimal draw and bright light makes them super--this is from a satisfied buyer, not an advertisement!

Yes , these are 12V panels .Under full sun , one panel can produce Around 17VDC .You will need a good solar controller to keep voltage to 12V to your batteries

Yes if connected to the right connector but you will still need a 12 volt power source for the led lights

I think that if the input voltage of battery is 12 V and the shapes of inlet are compatible, then you can use this solar panel directly.If the input voltage is not 12 V, the you can charge battery by car adapters.And I want to suggest that you should disconnect each other after charging battery. Because some one said that the panel discharge the battery while the sun is down.

In theory you can, but its not recommended and the NEC wouldn't approve. If you want to connect a 12 V battery to an inverter (to make it act as a power source) then look for an off-grid power inverter instead. They can come in 12V, 24V, 48V configurations.

Directly? Probably not. The output from the panel is DC. It needs a controller to settle it to c. 12+ volts (to charge battery.) If your radio works on 12v DC you are set. If it runs on 110v ac you will need an inverter (DC to ac).
